MHD-013 - Private tutor training

Shiina, a secretary who has been asked by the president to tutor his only son, invites him to his home. A young, sexually inexperienced son comes to a young woman living alone with vague expectations. However, what awaited him was a trap set by his stepmother, and an invitation from Queen Shiina to the masochist man. As he is trained in front of his stepmother, he gradually begins to feel the pleasure of being a submissive man, from being humiliated. With 4P training including his stepmother's exclusive slave, the bud of his masochist desire that was deep within his heart will bloom.
